while用法小结(包括与when的比较)(图10)While用法小结

While 用法小结:一、 while 用作名词时,意为“一段时刻,一会儿”。

例如: I stayed there for a short while. (我在那儿呆了一小会儿。

) The postman came a short while ago. (邮递员刚刚来过。

) 二、 while 用作连词时,有以下几种寓意: 1. 意为“当……时辰,和……同时”,引导时刻状语从句。

例如: While I was watching TV, the bell rang. (我看电视时,铃响了。

) Meimei watched TV while she ate her supper. (梅梅边吃晚饭边看电视。

) 2. 意为“尽管,尽管”,引导妥协状语从句。

例如: While it was late, he went on working. (尽管格外晚了,但他还在承袭任务。

) While he is in poor health, he works hard. (尽管他身子不行,但他依然努力任务。

) 3.引导条件状语从句 相当于 as long as,译作“只需”。

例如: While there is life, there is hope. (有性命,就有希冀。

) While a spark of life remains, it is a doctor's duty to save the patient. (只需病人还有一息生机,大夫就有责任挽救。

) 4.引导缘由状语从句, 相当于 since, 有“既然”的意义。

例如: You'll never save any money while you're so extravagant. (你那样简朴,永久存不 下钞票来。

) I'd like to get it settled today while we're at it. (既然我们着手干了,我想改日就把它 干完。

) 5. 衔接两个并列句子,显示“对照”关系。

例如: He went out for a walk, while I stayed at home. (他出去漫步了,而我却呆在家里。

) I like singing while she likes dancing. (我爱慕唱歌,而她爱慕跳舞。

) You like sports, while I prefer music. (你爱慕体育,而我更爱慕音乐。

) 三、 while 引导状语从句时,应留意以下几点: 1. while 引导的时刻状语从句既可放在句首,也可放在句末;而 while 引导的妥协状语从句 平常放在句首,不放在句末。

其它,也能够从意义上加以区分。

例如: While he was tired, he went on working. (尽管他累了,但他依然承袭任务。

) ( while 引导妥协状语从句) While he was tired, he would have a rest. (他累了就休憩一会儿。

) ( while 引导时刻状语从句) 2. while 引导妥协状语从句时,假设从句的主语和主句的主语相反,那样从句的主语和谓语 动词 be 都能够省略。

例如: While he was ill, he went there. (= While ill,he went there.) (尽管他有病,但他依然去那儿了。

) 3. while 和 when 都能够引导时刻状语从句,但应留意:while 引导的时刻状语从句中的

谓语动词务必是延续性的动词;而 when 引导的时刻状语从句中的谓语动词既能够是延续 性动词,也能够是非延续性动词。

事先间状语从句中的谓语动词是延续性动词时, while 和 when 能够相互交换。

例如: While we were talking, the teacher came in. (我们正在说话时,教员出去了。

) The bus had left when we arrived at the bus stop. (当我们抵达车站时,公共汽车曾经 开走了。

) ( arrive 是非延续性动词,因此,此句中的 when 不能用 while 交换。

) When / While we were having a meeting, our teacher came in. (我们正在休会时,教员走了出去。

) ( have 是延续性动词,因此,句中的 when 能够用 while 交换。

) 4. while 引导的状语从句还能够显示“某个举措正在停止的同时, 另一个举措也在停止之中”。

例如: While the teacher was speaking, the students were listening. (教员讲课时,先生们在听。

) While he was writing, I was reading.
